Abstract
A shake-proof camera comprises a shake-correcting lens portion for correcting a shake by changing an optical axis of a photographic optical system and a moving lens portion disposed in the vicinity of the shake-correcting lens portion and arranged as movable in a direction of the optical axis, and further is provided with a shake-correcting lens lock apparatus for locking the shake-correcting lens portion by bringing the moving lens portion into contact with the shake-correcting lens portion.
Claims19
A shake-proof camera comprising:
- a first lens functioning as a shake-correcting lens portion that corrects a shake by changing an optical axis of a photographic optical system in a direction substantially perpendicular to the optical axis, the first lens being used for shake-correction;
- a first lens frame that holds said first lens;
- a second lens, distinct from said first lens, functioning as a focusing lens portion disposed in a vicinity of said shake-correcting lens portion and arranged as movable in a direction of the optical axis, said second lens being moved for focusing without moving said first lens of said shake-correcting lens portion;
- a second lens frame that holds said second lens;
- and
- a shake-correcting lens lock apparatus disposed on said second lens frame and that prevents said first lens from moving in a direction perpendicular to the optical axis when said shake-correcting lens lock apparatus is in contact with at least a portion of said first lens frame.

- a shake-correcting lens lock apparatus disposed on said second lens frame and that prevents said first lens from moving in a direction perpendicular to the optical axis when said shake-correcting lens lock apparatus is in contact with at least a portion of said first lens frame;
- and
- a shake indication lamp to be turned on when the shake is less than or equal to a predetermined level, and to blink when the shake is greater than the predetermined level.

A shake-proof camera, comprising:
- a first lens functioning as a shake-correcting lens portion that corrects a shake by changing an optical axis of a photographic optical system in a direction substantially perpendicular to the optical axis, the first lens being used for shake-correction;
- a first lens frame that holds said first lens;
- a second lens, distinct from said first lens, functioning as a focusing lens portion disposed in a vicinity of said shake-correcting lens portion and arranged as movable only in a direction of the optical axis, said second lens being moved for focusing without moving said first lens of said shake-correcting lens portion;
- a second lens frame that holds said second lens and has a contact portion, the contact portion coming into contact with at least a portion of said first lens frame due to movement of said second lens in the direction of the optical axis, thereby preventing such movement of said first lens as to change a position of the optical axis.
